Alcohol Use Has No Effect on HIV Disease Progression in an Antiretroviral Naïve Cohort

In experimental studies among macaques, alcohol use has been shown to accelerate disease progression of simian immunodeficiency virus, but the results in observational studies of HIV have been conflicting. URBAN ARCH researchers conducted a prospective cohort study of the impact of unhealthy alcohol use on CD4 cell count among 446 HIV-infected persons in southwestern Uganda not yet eligible for antiretroviral treatment (ART). Unhealthy alcohol consumption was assessed by self-report and verified by phosphatidylethanol (an alcohol biomarker).

  • At baseline, 43% of participants had unhealthy alcohol use and the median CD4 cell count was 550 cells/mm.
  • The estimated CD4 cell count decline per year was -14.5 cells/mm for those with unhealthy drinking compared with -24.0 cells/mm for those refraining from unhealthy drinking. There was no significant difference in decline by unhealthy alcohol use, adjusting for age, sex, religion, time since HIV diagnosis, and HIV viral load.

Conclusion: Unhealthy alcohol use had no apparent impact on the short-term rate of CD4 count decline among this cohort. These results suggest that the impact of unhealthy alcohol use on HIV outcomes may be via mechanisms other than immune response, such as reduced treatment adherence and chronic inflammation.
